The open architecture is easy to extend and enhance
Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Alerting precision has reduced incident response times and improved department-level network visibility
The auto-pause sensor during the maintenance window is good without any false alerts, and it prevents me from getting flooded with alerts during planned maintenance, helping department heads understand their own network usage better. It has reduced incident response time by giving clearer ownership of each alert, ensuring alerts go to the proper recipient. SNMP testers and auto-pause are among the best features of PRTG Network Monitor, which is particularly useful for different departments such as HR and finance, where alerts can be filtered accordingly. The alerting features and dashboard of PRTG Network Monitor are very helpful, especially in our industry. However, the dashboard can look cluttered on smaller screens, which is one negative aspect. PRTG Network Monitor has impacted us positively; we have stopped getting flooded with alerts during planned maintenance or unplanned outages. Compared to others, this gives specific alerts very quickly and helps department heads understand their own network usage better, thus reducing incident response time so that each alert has clear ownership.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The official forum is active enough to answer most of the high-end technical questions that you may have."
"Pandora's architecture is interesting; it's open so you can easily extend and enhance it, it's simpler to customize Pandora compared to other solutions, and it's also scalable enough to support large environments."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"What I value most about Pandora FMS is the simplicity of working with it."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"The solution has good dashboards and graphics."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"The authentication links into our standard Active Directory authentication, which is very good."
"The auto-pause for sensors during maintenance windows is awesome, as there are no false alerts till now and the built-in SNMP tester tool has saved me multiple times during setups, making PRTG Network Monitor a one-stop monitoring solution for my industry."
"It is nice to have one place where all the information is right there in front of us."
"PRTG Network Monitor's best features are its flexibility, ease of implementation, user-friendliness, and intuitive interfaces."
"The scalability is good. You can improve a remote host or the clustering. This gives it the flexibility to monitor another infrastructure remotely."
"Every monitoring session features similar capabilities."
"It is very flexible, and we can monitor many aspects of IT as well as ERP and CRM services. It has a very powerful interface and APIs for customization."
"PRTG is integrated on Windows."
 

Cons

"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"Pandora could deliver better analytics out of the box."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas."
"They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way."
"We would like the real-time monitoring of an interface to be improved within this solution."
"I posed this question to PRTG and they were unresponsive, so it seems like not enough customers are complaining about it or would be potentially using it."
"For smaller networks, I would recommend this solution. That said, if the network is complex, I would recommend a company evaluates another product instead."
"PRTG Network Monitor could improve by having a feature to allow uploading of preset standard network switch configurations and the ability to monitor the SLA configuration, such as uptime for the switches or internet connectivity. This would be very useful."
"There are some vendor-specific sensors in PRTG Network Monitor, particularly for older hardware, that don't always provide consistent results."
"I am not sure the solution is giving me all the needed feedback that we need."
"PRTG Network Monitor can be improved because the dashboard themes feel outdated."
"I am not sure the solution is giving me all the needed feedback that we need. When something goes off on our IT infrastructure, it does tell me. However, it would be nice if it gave more intuitive information, e.g., the hard drive has gone up by 60 percent in an hour."
"The automation should be improved."
 

Pricing and Cost Advice

"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"My rule of thumb would be that if you need more than thirty agents, and you lack an automation tool such as Chef or Puppet, you will save a lot of time and money going to the Enterprise edition."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"You have to pay for the number of agents and models that you are monitoring. I would rate the cost at three with one being the most expensive and five being the cheapest."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"The ability to use the base version with 100 free sensors is great. The cost on other packages can be very reasonable."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"All monitoring system is close to the same pricing scheme."
"We pay for a perpetual license and we have a support fee."
"It is expensive."
"We pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."
"I rate the price of PRTG Network Monitor an eight on a scale of one to ten, where one is a high price, and ten is a low price."
"One thing I like is that when you buy sensors, it's a perpetual license, so once you buy 2,000 sensors, you've got 2,000 sensors; it's not a recurring cost."
